The goal of our lab is to to use photons for quantum information processing. To achieve this we have experiments to investigate the generation, storage, characterization, and manipulation of light suitable for quantum information applications. We study quantum light-matter interactions with atom-like emitters in solids, in particular rare-earth atoms that have excellent coherence properties. We are investigating quantum memory and single photon storage in solid-state rare-earth atom ensembles, including new materials to push toward the possibility of long-lived, efficient, solid-state quantum memory. Another project involves coupling rare-earth atoms to resonator structures to be used as sources of single photons and spin-photon entanglement. Finally, additional projects focus on generating, characterizing, and using photon pairs for quantum information tasks.
New materials for quantum memory
We develop new rare-earth crystalline materials with ultra-high densities of emitters to better understand atom-scale effects on the quantum properties of the atoms and to engineer better quantum memories for light.
Quantum integrated photonics
We us thin film lithium niobate doped with erbium atoms to store and manipulate light on chip. By fabricating high-Q photonic structures we can dramatically increase the light-atom interaction and enable new functionalities.
